I use these to aerate my pond. Worked great since last year when I purchased. Ordered another couple to replace one that arrived broken when purposed.Turns out they delivered the RAD850 (non-weighted) instead of what I had ordered. Before I was able to report/return, I received today the correct ones.This is a company that has a quality shipping and order reconciliation processes.

I bought a couple of 12 inch non-weighted diffusers. They are solid quality. And yes they do sink despite the description. I used it at the shallow end of my pond, about 20 inches or so deep and they stay down without issues. I don't know if they will go super deep, but my guess is they would. I hooked 2 of these together with a T-barb to a Medo 80 pump and they put out tremendous amount of air. For $25 each, it's definitely very good.
